April 15, 2021 - Corrected error in NLCD2006 and NLCD2011 tables
- There was and error found in the NLCD 2006 and NLCD 2011 tables that were published to LakeCat that have now been corrected - the values reflected the previous release of these two NLCD years rather than the NLCD 2016 product versions of NLCD 2006 and NLCD 2011.
February 1, 2021 - Updated metrics in several tables to fix watershed areas for some COMIDs in Hydroregions 2 and 13
- There was an update to StreamCat code to flow table connections in Hydroregions 2 and 13 that altered watershed areas slightly for a number of COMIDS. This affects lakes that are 'on-network' and use StreamCat results. Several metrics in LakeCat hadn't been updated to reflect this update and the following LakeCat final tables were updated:
- Dams.csv
- ImperviousSurfaces2016.csv
- NABD.csv
- PRISM_1981_2010.csv
- ImperviousSurfaces2001.csv
- ImperviousSurfaces2006.csv
- ImperviousSurfaces2011.csv
- WetIndx.csv
- NADP.csv
January 8, 2021 - Added all NLCD 2016 and Impervious 2016 years

October 30, 2018 - Update Wetness Index
The Composite Topographic Index (CTI) generated by EnviroAtlas used to generate the Wetness Index in LakeCat was recently updated. The Wetness Index in LakeCatCat was re-calculated using this updated, corrected CTI raster from EnviroAtlas.
